Whatever you call them in game. read up on what WM_MOUSEMOVE sends as lParam and wParam. Then you need to setup a camera system in your game. After that you need to add code in there to move the camera depending on how you moved the mouse.

I was just observing the behavior of those buttons and came to a conclusion that I just need to change the directions to -direction in the formula used to control the W and the S and the A and the D and they all work nicely now
